REID, Oil' SHAKER HEIGHTS, OHIO, ASSIGNOR TO TEE REID PRODUCTS COM'.- PAN'Y, OF CLEVELAND, OHIO, A CORPORATION OF OHIO GLASS RUN CHANNEL STRUCTURE Application led August 6, 1931. Serial No. 555,518.

The invention of this application relates to glass run channel structures for use with the windows of motor vehicles and the like.

The object of the present invention is to combine finishing strip and glass run channel features, wherein the channel structure includesan outer main channel adapted to flt snugly within a window groove and preferably made of a non-metallic material, such as paper to prevent chattering and other noise, said channelhaving polished-finishing strips applied to` the upper edges of each of the side anges thereof. Such channel structure also includes a pair of lip pad strips of spring metal or the like projecting inward from the channel side anges and secured thereto by lugs integral with said lip pad strips and extending through slots in said channel side flanges. Suitable cushioning means. is, of course, provided for the glass? engaging portions of said lip pad strips and for the inner surface of the bottom of the main channel. y'

Another feature of the invention is one wherein the main outer channel, having the nishing strips, is made of two separate channel portions, each including a side ange and abase flange and each side flange provided with a lip pad projecting inwardly therefrom, the two half-channel portions being secured in place by a separate base member forced down between the side flanges of y the two channel portions against the base -iianges This base member is preferablyprovided with a suitable cushioning pad for engaging the edge of the glass.

Another feature of .the invention is an arrangement of the base portion of a unitary outeror main channel, of paper or the like, bulged upwardV in such a way as to form a cushioning yielding base 'for engagement with the edge of the glass and of a construction such that its depression causes the inner or base edges of the side anges to be forced o ut against the sides and into the corners of the window groove.

The i yvention is wellset forth'in the following escription, ,drawings and claims.

Referring to thel'drawings, Fig. l is a view, partly in section and partly in eleva"- tion, showing the channel structure applied y to a portion of the window frame; Fig. 2 is an enlarged view of a portion of the lip pad members removed from the main channel; Fig. 3is an enlarged view of the main channel with the lip pad members removed; Fig. 4 shows a modified form wherein vthe main channel is made up of two side channel portions and a separate base; and Fig. 5 is a similar view showing still another modiied form wherein .the main channel is of substantially -U-shaped form with the base bulged upward to provide a yielding glass ed e-engaging portion.

eferringito the drawings, 1 represents lthe frame of the window provided with a window groove, indicated at 2. v,Within-this window groove the channel structures herein described are applied.

In the channel structure shown in Figs. 1, 2 and i3, the outer main channel of nonmetallic -material, such as stiff waterproof paper, comprises a base 3,) and side flanges 4. Each of these side flanges is provided along its outer edgeA with a finishing strip comprisi ing the two side portions 5 and -6 and the top loop or cross portion 7. Each of the side flanges is further provided with longitudinal slots 8,"spaced 'longitudinally therealong a short distance a'bove the base, as shown in Fig. 3.

Engaging the side flanges are the lip pad strips, each of which comprises va vertical longitudinally extending strip ortion 9 and an inwardly diagonally' exten ing lip por. tion 10, beaded over as at 11. At the lower may be covered by an inner covering 13 of rubber and an outer felt layer 14, a suitable bead or thickened rubber portion 15 being A provided around the outer edge. Y

From the foregoing, it will be seen that the spreading tendency of the glass causes the lip pad strips to bear at substantially the polnts marked 16 against the inner` faces of. the side flanges of the main channel, causing a pull inward on the tongue, which through the downwardly bent portions on the outside hold yand resist this movement, resulting 1n the lip pad strips having a -yieldmg actlon upon the glass. A channel structure of this type is noiseless and readily adapts itself to the window groove and fulfills all the desired window channel requirements.

In the modification shown in Fig. 4, the main channel is made up of two separate side channel portions, including side flanges 17 and base flanges 18. Forced down between the side flanges and engaging the base flanges 18 is a bottom strip 19 provided with a suit* able pad 20 on its upper surface. Y When the bottom strip is in place the two channel portions are held in' proper position in thevg'indow groove. Inv this arrangement the same lip pad strips as set forth inFigs. 1 to 3 are employed and need no further description.

In the modification shown in Fig. 5,- the l main channel includingside flanges 21 and 22 is provided with a curved base member 23, whlch may be a separate piece, as in Fig. 4, or may be integral with the side anges.

Havin described my `invention, I claim: 1. A glass run channel structure, com rising a non-metallic generally U-shaped c annel member having side filanges and il. b ase portion, finishing strips at the outer edges of said anges, and a pair of glass-engaging lip pad strips, one for each of said side flanges,

each of said lipfpad strips comprising a main strip portion engaging theinner surface of one of said side anges, a glass-engaging padded lip portion secured to said main stnp portion and means integralfwith said main strip portion for securing the same to one of said side flanges.

forth in claim 1, characterized in that the securing means for said lip pad strips comprise tongues integral with the main stri portions of said strips. and characterized ipurther in that the side flanges of said channel member are provided with slots to receive said tongues.

In testimony whereof I hereby aiiix my signature.
